AMSOIL Synthetic 10W-30 / SAE 30 Heavy Duty Diesel Oil (ACD) is formulated with premium synthetic base oils that provide outstanding performance in modern and older diesel engines. This premium synthetic diesel oil provides better fuel economy while it protects against damaging piston deposits, ring sticking and sludge.

Recommended for use with low or high sulfur diesel fuels in standard, turbocharged or supercharged engines. Including modern low emission diesels such as those equipped with EGR systems.

It has a -36F pour point and qualifies for SAE 10W, making it an all season multi-grade lubricant with a wide operating temperature range. This shear stable formulation stops viscosity loss and associated bearing and cylinder bore wear. AMSOIL ACD contains premium additives with a high 12 TBN to neutralize acids from blow-by, exhaust gas recirculation (EGR) and high sulfur diesel fuels.

AMSOIL, the leader in automotive synthetic lubrication, produced the world's first API qualified synthetic motor oil back in 1972. Trust the extensive experience of AMSOIL
 The First in Synthetics® to do the best job protecting your equipment.

Whether it's diesel performance you're after or the hottest truck accessories. We've got parts for all models from 1999-2008 in stock and ready to ship (for free!).

Where these viscosity grades are specified, AMSOIL Synthetic 10W-30 / SAE 30 Diesel Oil (ACD) provides outstanding performance as a straight-grade SAE 30 for older two- and four-stroke diesels and as a multi-grade SAE 10W-30 in modern four-stroke diesels as well as gasoline engines. AMSOIL ACD is ideal for use in a wide variety of light and heavy-duty applications, including agriculture, off-road construction, trucking, mining, industrial (pumps and generators) and personal automotive or commercial transportation.

Class 8 Diesel Trucks Achieve 8.2% Better Fuel Economy with Amsoil Lubricants

This superior synthetic diesel oil costs a few dollars more but lasts far longer than other diesel oils. This can save you 50% on oil change expenses. And you can add the savings from better fuel economy on top of that. You get maximum performance, improved fuel economy and lower maintenance costs.

AMSOIL Synthetic 10W30 / SAE 30 Diesel Oil is recommended for use in diesel engines and other applications requiring any of the listed worldwide specifications and gasoline engines including API SL, SJ, SH or ACEA, A3 and the following:

AMSOIL ACD is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed. Aftermarket oil additives are not recommended for use with AMSOIL motor oils.

AMSOIL Synthetic 10W-30 / SAE 30 Diesel Oil is recommended for extended drain intervals in unmodified(1), mechanically sound(2) vehicles or equipment as follows:

Commercial or Fleet Vehicles, Long-Haul Trucks, Marine Craft, RV, Off-Road Equipment

Non-EGR equipped diesels -- extend drain intervals up to two times (2X) the OEM* recommended drain interval or one year, whichever comes first, or longer based on oil analysis.

EGR equipped or low emission diesels -- extend drain intervals based on oil analysis or use the OEM* recommended interval.

Replace Donaldson Endurance™ or AMSOIL Ea™ full flow oil filters at the time of oil change up to two times (2X) longer than the OEM* standard interval, not to exceed 60,000 miles in long-haul trucks.

Personal Light Truck Diesel Engine Service

Donaldson Heavy Duty Endurance Oil and Air Filters reduce maintenance costs and increase fuel ecoomy

Normal Service(3) -- Up to 25,000 miles or one year, whichever comes first, or longer based on oil analysis.

Severe Service(4) -- Up to 15,000 miles or one year, whichever comes first, or longer based on oil analysis.

Replace AMSOIL Ea full flow oil filter or Donaldson Endurance ELF 7349 at the time of oil change up to 25,000 miles (other brands at standard OEM* intervals).

Gasoline Engine Service

In gasoline engines, oil drain intervals may be extended up to two times (2X) the OEM* recommended drain interval (not to exceed 15,000 miles without oil analysis) or one year, whichever comes first. Replace AMSOIL Ea™ full flow filter at the time of oil change up to 25,000 miles. Replace other brand oil filters at standard OEM* intervals.

*OEM = Original Equipment Manufacturer

(1) Where the engine or operating conditions have been modified from the original manufacturers' design, no oil change interval recommendation is made. Oil change intervals are at the owner's discretion. Examples include the use of performance computer chips; modified exhaust, fuel or air induction systems and the use of fuels other than those recommended for normal operation by the manufacturers.

(2) Engines are in good working condition and within the factory design settings. Mechanically sound engines, for example, do not leak oil or consume excessive amounts, are not worn out, do not overheat, do not have internal or external antifreeze leaks and have a properly working emission
control system. AMSOIL recommends repairs be made to malfunctioning engines prior to the installation of AMSOIL synthetic oils.

(3) Personal transportation vehicles frequently traveling greater than 10 miles (16 km) at a time and not operating under severe service.

(4) Extensive engine idling, daily short trip driving less than 10 miles (16 km), frequent towing, plowing or hauling heavy loads and frequent driving in dusty conditions.

AMSOIL Ea™ and Donaldson Endurance™ full flow oil filters are designed for extended drain intervals. They stop smaller particles, have less restriction and last longer than regular filters. For best performance, use AMSOIL Ea or Donaldson Endurance oil filters. AMSOIL by-pass oil filters are specialized for the removal of small, wear-causing dirt particles, thereby extending engine and oil life. AMSOIL encourages using an AMSOIL bypass filter system for maximum engine and oil life.
